The present list is based upon a paper on the genus Catocala recently published in the Transactions of the American Entomological Society. The sequence of the species there adopted is here retained, with an unimportant change in a single instance for convenience of reference. The species are grouped according to the colour and design of the hind rvings. Such an arrangement must, to a certain extent, be arbitrary, yet little violence seems to be done to the general affinities of the species by its adoption in this genus.
